ALBA LIGHT LAMP.

SPECIFICATION forming part of Letters Patent No. 269,466, dated December 19, 1882. Application tiled June 21, 1882. (No model.)

To all whom it may concern:

Be it known that I, WILLIAM BURNET ROB- INS, ofCincinnati, Hamilton county, Ohio, have invented a new and useful Lamp, of which the following-is a specification.

My lampis moreparticularlyintended for use with kerosene and kindred forms of petroleum and coal oils, and has for its leading objects economy of material with high illuminative to properties and convenient and cleanly manipulation of wick, together with complete safety.

In the accompanying drawings, Figure l is a partially-sectioned elevation of a lamp embodying my improvements. Fig. 2 is a top view of the same without its shade, central deflector, and chimney, the base of the standard being omitted. Fig. 3 is an external view of the needle-rack column or housing, and portions of the font and its supporting inverted 2o siphon. This figure contains a sectional representation of an adjustable form ofmy shadebracket, of which Fig. l is a top view. Figs.

5 and 6 are sections of the rack-housing at l l and at2 2, respectively. Fig. 7 shows the wick carrier and holder detached, a portion of the Wick-elevating needle being seen attached to the carrier.

A pedestal of suitable height and dimensions affords support to the inverted siphon 0 B, whose longer arm bcommunicates with and supports, in a sufficiently-elevated position, the font or reservoir C, from whose floor, where it communicates with said siphon, rises a hollow column or housing, D, forarack, E, which 3 is guided to a vertical path by the walls of said housing and by partition F. A pinion, G,journaled in said housing and havinga handle, H, external thereto, enables vertical shifting of the rack at discretion of the user. 801- dered or otherwise permanently attached to the said rack is a steel rod, 1, called by me the needle! This rod occupies the inverted siphon or oil-duct B, and protrudes through both ends of the same, and has its other extremity 4 5 soldered or otherwise permanently fastened to a short tube,J, which I call the wick-carrier. The wick-carrier J has a flange, j, thatprojects horizontally from its upper edge, and has two diametrically-opposite uotchesj, (of which one only is here shown,) for reception ofhooks rests upon said l from similarly-flanged lower end of a similar but longer tube, L, which I call the wickholder. This tube has preferably a congeries of orifices, 1, near its lower end. To the holder L is fastened a suitable tubular wick, M. The wick, with its holder and carrier, and attached extremity of the operating-needle, occupy and play vertically within an annular wickway, N'N N, which is soldered or otherwise rigidly fastened to the upturned shorter 6o limb b of the inverted siphon B. Of the two concentric tubes that constitute the walls of the wickway, the inner tube, N, constitutes the outer wall of annular draft-inlet 0, whose inner wall is constructed as follows: A bridge, P, which stretches athwart the lower end of the tube N, supports, coincident with its axis, a tube, Q, of rather smaller diameter.

Over the tube Q is slipped a closely-fitting tubular cap, R, which, being crowned by a projecting disk, S, operates to detlect toward the annular sheet of flame the annular current of air from the draft-inlet O. Pins T or any other suitable provision upon either tube Q or R prevent the cap R S descending below its proper position for efficient service as deflector.

A gallery or collar, U, which encircles the wickway, has numerous minute oritices u to admit draft-air to the outer draft-inlet, V, whose inner wall is formed by the outer tube,

N, of the wickway, and whose outer wall is formed by the truncated hollow cone W, which gallery U. A shoulder, to, on cone W serves as aresting-place for a glass chimney, X, of any proper form. This construction is exceptionally free from liability to spillage of oil, wick fragments, 850.; but for abundant security a drip pan or catcher, Y, may be affixed to the oil-duct B.

The rack-holder or housing D may be utilized for attachment of a bracket, 1, to which is secured by hinge 2 an elastic clasp, 3, for suspension of a shade or reflector, 4. The hinge 2 permits the clasp 3 and its appended 5 shade 4 to be folded back to position shown by dotted lines in Fig. 1 when desired.

. The bracket 1 may be immovably attached to the housing D, as in Fig. 1, or may be made capable of sliding up and down upon it, and of being secured at any desired elevation by setscrew 5, as in Figs. 3 and 4.

The location of the wick-operating handle remote from and out of the vertical line of the burner entirely avoids any heating or soiling of the handle, and reduces to a minimum impediments to the free radiation of light,whether from the users hand orotherwise, while the similarly-isolated location of the font avoids any dangerous heating of its contents.

The described form and arrangement of concentric tubes and disk-deflector, which cause the interior air to rise at first in a uniform annular cylinder or sheet, and subsequently to project radially and obliquely upward toward the interior wall of the flame-sheet, coacting with the obliquely inward and upward annular draft-sheet from the outer deflector, are found to produce an intensely white and remarkably even flame.

The removability of the tubular cap or thimble R S enables the easy trimming of the wick and the cleaning of the central air-passage, and also enables the substitution of a new tubu'ar cap or thimble when necessary.

am aware that annular interior draft-inlets are old and well known, and therefore make no claim to such, broadly considered.

A subsidiary but valuable function of the I needle is that of agitating the liquid contents and preventing any lodgment of sedimentary matters.

Besides the effects above mentioned, very important economic results accrue from the presence of the tubular extension It Q from the highly-bean d disk orbutton S. Said tubular extension, being a good conductor, becomes itself highly heated, and operates beneficially, both by preheating the interior annular sheet of draft-air and, operating chimney-wise, in

stimulating the atmospheric up-rush, thus causing contact of rapidly following volumes of heated air with the inner face of the flamesheet. The thus heated air is further beneficial in that it raises the temperature of the oil within the wickway, and, by expanding and partially vaporizing it, facilitates its combustion.

The described mounting of wick-tube by its extreme lower end upon the extreme delivery end of the J-shaped oil-duct secures the utmost practicable thermal insulation of the wickway by reducing to a minimum the robbing of its heat by said duct, such as always occurs with the customary attachment of the duct at or near the mid-height of the wicktube. My construction consequently secures two important ends, to wit: First, the heat being retained in the wick-tubes, rarefies the oil-vapor and air-currents; secondly, wasteful and dangerous overflow of heat toward the font along the metal connection is reduced to a minimum. 7

The above-described preferred embodiment 'of my invention is obviously susceptible of various modifications. For example, the font may have a central sleeve to fit around a vertical stem, and be provided with two or more inverted siphon-ducts radiating from it at different parts of its circumference; or a font with a number of such radiating ducts may have projecting from the middle of its crown a vertical stem terminating in an eye, by which to suspend it from a ceiling; or the font may have one flat side with wall-plate extension to hang onto a column or other fixture.

The described J-formed duct and its contained operating needle may be associated with a flat wick with correspondingly flat carrier and wickway.

I claim as new and of my invention 1. In combination with the inverted siphonpipe B, connecting the wickway with the oilfont, the flexible rod or needle I, made fast to the wick-carrier and traversing said pipe and font to a point of convenient manipulation, substantially as and for the purpose set forth.

2. The combination, with the inverted siphon-duct B, that connects an elevated font with the wickway, of flexible rod or needle I, which occupies said font,duct, and wickway, and which connects at one extremity with a means for giving it a longitudinal movement, substantially as and for the purpose set forth.

3. In combination with the inverted siphonduct B, connecting the distant font 0 with the wickway N N N, the font 0, provided with the hollow standard D, containing the rack E,

carrying needle I, the guide F, pinion G, and operating-handle H,substantially as and for the purposes specified.

4.- In combination with the column or housing D, the needle-operating mechanism and the bracket 1, with attached clasp or holder 3 of lamp-shade, substantially as set forth.

5. The described combination, with elevated font, inverted siphon-duct, and wickway, of the included wick-operating needle I, and attached rack E, and pinion Gr, substantially as set forth.

6. The wick-tube L, provided with hooksl and orifices Z, in combination with the wickcarrier J, having ,flangej and notches j, and the attached needle I, substantially as set forth.

In testimony of which invention I have hereunto set my hand.
